Specification of Letters Patent.

Application filed November 16, 1908. Serial No. 462,876.

publieo'f Switzerland, (Whose postoffice address'ls Ruth) have invented certain new and useful Improvements in Double-Lift Open-Shed Jacquard-Machines; and I- do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable 0 er's-skilled' in the art towhich it appertains to make and use the same,'reference being had to the accompany.

- mg drawings, and to numerals of reference the marked thereon, which form a partof this specification.

. The double-lift open shed jacquard machine represented in the accompanying drawings belon s to that. class whi'chshows groups of griff b ades, lying side by side, and where one .griff blade of theone group works alternately with one gri'lf blade of the other group. Accordln to this invention each hook of the doub e-lift-open shed :jacqua'rd machine possesses besides the. two" usual hooks proper for the engagement with the griif blades, a special hook proper, which is intended .solely for the hanging up 'of the hook to a fixed hook-rail, extending over the whole breadth of the machine, .for the purpose 'ofopen-she'd position. Further, for ose of-displacin the hooks proper "ll of the ooks which con d, when the griff blades are in their middle position, engage with the. griff blades, there are arranged fixed rails forming'a cam. This cam is for the purpose of'diverting the hooks, so that.

'the hook proper of each hook shall be brou ht out of reach of the respective rising riff lade, which should not engage with the atter. 1

Through the automatic diversion of the hooks a considerable constructive simplifying and safer working is insured against the former looms; having special diverting devices (such as movable rakes, grilles, etc.).

A loss of power and wearing away of the carrying-planes of the hooks are avoided with the present invention the friction being confined only to those hooks which change theirposition. The movable parts of the present-machine have been reduced to a minimum.

In the accompanying drawings an example. of the object of the invention has been reprebook 5 comprises three arms 6, 7 and 8 andfour hooks proper 9, 10, ll'and 12 and a nose 11 0 each hook 5 are intended to engage with the griff blades 14 and 15 whereof the one 14 belongs to'one group of griff blades the other 15 to the other group. I The middle arm 7 of each book 5 extends beyond the I other-arms or shafts 6 and 8 and bears the hook proper 10, which isintended for the hanging up of the hook onto the hook rail 16, extending over the whole breadth of the machine. The book roper 12 of each hook is' destined to-lay itse f, when the hook is in its deepest position, upon a carrying rail17, which also. extends over the whole breadth of the machine. The diverting rails v18, in the form of wedges or cams, are so fixedly arranged on the frame of the loom, that they lie in the line of the hook noses or tap ets 13 when the hooks descend'in their eepest position. p

In Fig. 1 where the card cylinder 1 has been moved off the hook needles 3, andwhere the middle position of the griff blades is supposed, the nose 13 will be, when in the position I of the hook 5, on the thickest part of the diverting rail or cam. The shafts 7 and 8 "withthe hooks proper 10 and 11 are thus diverted to the rlght, so that at a turning back of the loom the hook will not be lifted the shaft 11 of the rising griff blade 15, so

or taippet 13. The two hooks proper 9 and that the'hook does not remain in the open shed position.

In position II the hook 5 is in its lowest position. As the nose or tappet 13 has passed over the divertingrailflor cam,. no diverting of the hook 5 happens. The latter is thus in the ready posit1on to be lifteda by the griff blade 15 in its next rising.

In position III the hook 5 is in the highest position and the hook roper 10 is hung in the hook-rail 16. The ook remains in this open shed position, until it will be pushed aWa from the hook-rail 16 by means of the car cylinder and the needle belonging thereto. At each rising of the griff blades 14 and position and its hooks proper 9 and 11 are hook from the hook-rail 16 is possible at the touch of the card cylinder upon the respec ave been diverted from the reach of the pet 13-, while the hook proper 1 1 is supported .and the griii blades 15 in their lowest posineedle and it is in its lowest position.

15 the hook hung u on the'hook-rail 16 will be lifted so much, t at a moving away of the tive needle. v

In position IV' the hook is in the middle position and the shafts 9 and 10 of the hook griff bladed'by means of the nose or tape y the grifi blade 15 going down.

In Fig. 2 the card'cy linder 1 is represented in the position of the touch upon the needles 3. The griff blades 14'are in their highest tion. Inposition V the hook 5 is in the lowest within the reach of the griff blades 14 and 15, ready to risewiththe gritf blade 15.

In position the hook, which lieswithin the reach of the grifi blades 14, 15 is in-the o en shed osition, as the hook proper 10 of t ehook is ung onto the hook-rail 16 and remains so, as long as the hook is pushed aside by the needle.

In position VII the hook 5 has been brought quite out of reach of the grill blades 14 and 15.by means of the card cylinder and In position VIII the hook 5 is in the high by side, means whereby one bla est osition'. The hooks proper 10 and 11 are Erought out of the reac of the hook-rail 16 and the grifl blades 15 by means of the card cylinder and needle, '.while the hook pro er'9 is engaged with the griii blade 14, rea y to descend with the same.

The hooks represented consist of two parts soldered together. One of them comprises the two'shafts 7 and 8, the other the shaft 6,

with the blades, and a thir hook for open I shed position, a fixed hook rail with which the third hook is adapted to' engage, fixed lower rails forming cams, and adapted to divert the blade engaging hooks, and tappets on the hooks adapted to engage with said cams.

' In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
